iPad 2 - white or black? wifi or 3g? 16gb or 32gb?Looking to purchase an iPad 2? How then do you choose between the white or black model? Or how about storage – 16gb vs 32gb? And of course do I need wifi or 3G? With so many options, how do you determine which is right for you?

Wi-Fi or 3G + Wi-FiThe iPad 2 has two different network connectivity methods – Wi-Fi or 3G. The 3G version of the iPad 2 will obviously set you back a monthly fee from your wireless carrier but is it really necessary? With so many Wi-Fi hotspots becoming more available day by day, you might consider opting for the Wi-Fi only especially if you already use a smartphone like the iPhone. With iOS 4.3 you get a hotspot feature that will let you use your phone as a mobile hotspot which really eliminates the need for 3G. Also, a large majority of Android smartphones now provide hotspot functionality. So, save the money and go wifi only.

16gb or 32gb or 64gbIt is my humble opinion that unless you are have an extensive library of music, photos and/or videos, that the 16gb model will be plenty of space for your everyday use. The typical user will have apps (which don't take up a lot of space) and a smattering of audio files consisting of music and podcasts – not enough to warrant the 32gb or 64gb price difference.

In addition, with iCloud and other cloud services, you can easily store files and acquire more storage as needed.

Black or whiteThe black iPad features a more consistent overall design. It looks as though the iPad 2 was originally designed to be black, and the white model is an afterthought. The black color matches the buttons and Apple logo on the iPad, and the end to end glass surface looks a bit cleaner in black.

The white iPad actually incorporates three colors. The bezel is white, of course, but the buttons on the side are black, and the back is silver aluminum. The white color tends to make fingerprints less noticeable but scratches and dings will be more easily visible.

One benefit of the white model is that it is better suited for outdoor use, particularly in the sunlight and heat. The white color reflects the sun's rays, ensuring that the unit remains cool throughout a session of use. The black model, on the other hand, absorbs more heat from the sun, so it is more susceptible to overheating during outdoor use but in all actuality is that a real concern.

I think the biggest consideration comes down to being able to view the content on the device. The contrast on the black model looks more vibrant than on the comparative white model. Maybe that is why TVs are mostly black.

In summary, I suggest that you choose the black/Wi-Fi/16gb model and with it you will end up with an amazing piece of technology for around $500 with some room to grow.
